Communication failure with mach 3
« on: June 30, 2012, 01:52:18 PM »
Last night I was working on my machine and everything worked well, this morning I turned everything on and it seems I have no communication to my breakout board, which is a sound logic supplied by Bob Campbell, charge pump won't activate to turn the drives on, and it does not acknowledge a signal from the limit switches, it seems like the program and or the computer not working together

I tested the breakout board per manual and everything seems to be working fine, the mach 3 program on computer seems to be working normal as always, I haven't a clue what's wrong.

Is there some way of testing to see if I am getting signals through the parallel port???   Thanks Darren

Hi Darren,

If you are running XP or 2000 then this little application will show the state of your parallel port http://www.geekhideout.com/parmon.shtml
